15. internal combustion engines of the motor trucks, the object of our invention being to provide simple, inexpensive and easily ..erated. controlling mechanism whereby t e agvalveson the internal combustion engines of 200i imotor. trucks are readily actuated and controlled. I

- e To the above purposes, our invention consists in-certain novel features of construci tionand arrangement of parts, which will be 2 hereinafter more fully set forth, pointed out in the claims, and illustrated in the accompa'nying drawings, in which:

Figure 1 is a plan view of a motor truck equipped with our-improved valve control- 39 ling mechanism; Fig. 2 is a side elevation 0f the truck as seen in Fig. 1; Fig. 3 is an enlarged vertical section taken on the line 3-3of Fig. 1; Fig. 4 is an-enlarged elevation-looking in the direction indicated: by the arrow 4, (Fig. 2); Fig. 5 is an enlarged vertical section taken on the line 55 of 'Fig. 1; Fig. 6 is, a horizontal section taken on the'line 6-6 of Fig. 4; Fig. 7 is an enlarged transverse section taken' on the line. 7-7' of Fig. 1; Fig.8is a horizontal section taken on the line 88 of Fig. 7; Fig. 9 is an enlarged transverse section taken on the line 9-9 of Fi 1; Fig.. 10 is an elevation of a reversing. evicewmade useof on our improved motor truck, Fig. 11 is a vertical sec- I tion taken longitudinally through the center of one of the engine cylinders of our linroved truck, and showing the inlet and exhaust valve in said cylinder; Fig 12 is -a horizontal'section taken on the line 12-12 of- Fig. 11;: Fig. 13" is a vertical section taken on-the line13-13 of Fig. 11.

-. In the construction of the truck as shown, we make use of a pairof side frames 1, which are "rovigled with the usual journal boxes 2, mw' hic'h the ends of the axles 3, carrying the carfwheels 4" operate. Fixed to the side frames 1', at points "adjapent the journal boxes 2, are arch bars 5, each of which sup" ports a pair of enginecylindersfi, which face one. another and said cylinders being connected by the hollow crank chamber casing 7, in which is journaled the transversely arranged engine shaft 8. Loosely mounted on the engine shaft 8, adj acentthe crank'casing, is a sprocket wheel 9, Which is engaged by an ordinary clutch'lO, which is fixed on said engine shaft; and fixed on one of the axles 3,

'in alinement with the sprocket wheel 9, is a sprocket wheel 11; and said sprocket wheels are connected by a chain 12.

Fixed on the engine shaft on the opposite side of the crank casing from the clutch 10 is a flywheel 13, and arranged for rotation in bearings 14 fixed to the topof the crank casing is a transversely arranged shaft 15, which is driven by suitable gearing, such as 16,

from the'engine shaft 8. Fixed on the end of the shaft 15, adjacent the sprocket wheel 9, is a commutator 17, of ordinary form, surrounded by the usual'casing 18, which carries the contact points 19, and which latter are electrically connected with the spark plugs in the ends of the engine cylinders 6. Fixed t0 the casing 18 and extending downwardly therefrom is an arm 20, to the lower end of which-is pivotally connected a link 21, and the upper end of said link is pivotally connected to a horizontally disposed lever 22, which is fulcruined to a bracket 23 extending downwardly from the car body. Connected by a ball and socket joint 24 to the opposite end of the lever 22 is a horizontally disposed rod 25, and formed on or fixed thereto is a plate provided with an aperture 26..

27 designates a carbureter, of ordinary form, into which leads an air pipe 28, and a liquid hydrocarbon pipe 29; and extending upwardly from the controlling valve on the interior of said carbureter is a stem 30, the

upper end ofwhich is bent horizontally, as

designated by 31, and said horizontally bent portion extends through the aperture 26..

Each engine. cylinder is provided. on top with an integral housing 32, the chamber on the interior ofwhich communicates withthe interior of the cylinder by means ofa port 33, and one endof the chamber in the housing 32 forms exhaust port 34, inwhich is arranged an exhaust valve 35 the stem 36 of which extendsto the exteriorof the housing 32, and there bein'g'an. expansive coil spring 37, mounted on said stembetween the housingrand the washer held upon the stem.

he springs '37 normally hold the exhaust valves 35 closed until the stems 36 are enaged by the outer ends of rods 38, which are held to slide through bearings 39 integral with the crank casing, and the inner ends of said rods being provided withanti-friction rollers 40 which are engaged by cams 41 fixed on the shaft 15. These cams are set to op- 32, opposlte the exhaust port, is a gas inlet port 45, and closin the outer end thereof is a plate 46,.with which is formed integral an outwardly projecting lug 47 the exterior of which is provided with a thread or'threads having an extreme pitch. Arranged to slide through the lug 47 is a stem 48, the inner end of which carries a valve. 49, adapted to close the passageway. between the port 45 and the port-33, and arranged formovement upon the'screw threaded u 47 is a collar 50, rovided. with an integra arm 51.

interposed between said disk and the collar 50 is an ex ansive coil spring 53.

Leading rom the carbureter 27 to each of the housings 32 and communicating with the inlet ports 45 are tubes 54, which convey the gas or carbureted air to-the engine cylinders,

after which said gas or air is ignited.

Pivotally connected to. the upper ends of Q I each pair of arms 51 are the horizontally arranged rods 55, the outer endsof which are connected to the lower ends of arms 56,,

which arefixed to and extend'downwardly from the ends of a rock shaft 57, journaled in 1 64, and arranged for rotation on said tubular.

' suitable bearin s carried by an oppositely arranged pair o the enginecylinders 6; and

fixed to therock shaft 57 is an upwardly rojecting arm 58, which is connected, by a all .and socket joint 59 to a transversely ar-= ran ed rod 60. i

ounted on the platform or fioor of the car su' vertica y disposed shaft 61 on the upper end of which is fixed a handle 62 and arranged for rotation on said shaft is a tubular shaft 63, provided atits upper end with a handle j shaft 63- isa tubular shaft 65, provided on its upper end with. a handle 66. Fixed respectlvely on the lower ends of the shaft 61,

tubulanshaft 63, and shaft 65 are thelaterally projecting arms 67, 68, and 69.

Arranged for rotation 'in suitable bearings 7 0, depending from the under side of the car body, 1s a sleeve 71 in which is held for rota-' tion a tubular shaft 72, and in which latter'is' 7 Locate on' the outer end of the stem 48 is a disk 52, and

orted by our improved truck is a which action necessarily arranged for rotation a shaft 73; and the forward ends of'said sleeve, tubular shaft, and

shaft terminate ad'acent the lower end of the verticall dispose shaft 61 and fixed re: s ective y on said sleeve, tubular shaft, and shaft, are the depending arms 74,7 5, and 76, the lower ends 0 which are respectively connected by ball and socket joints to horizontally arranged rods 77, 78 and 79 to the arms 67, 68, and 69. I j

The sleeve 71, tubular-shaft 72, and rod .73

are preferablyformed in sections of suitable length, and the ends. of one air of sections terminate adjacent'the cran casing 7 and connecting the adjacent ends of the sections ofthe rod 73 is a U-shaped link 80, the lower end of which is connected by means of a ball and socket joint 81 with the end of the rod 25, opposite the end that connects with the lever 22.

The adjacent ends of the sections of the tubular shaft 72 are connected by a U-shaped member 82, the lower end of which is connected by means of a ball and socket joint-83 with the end of the rod 60, opposite the end that is connected to the arm 58. a

The adjacent ends of the sections of the sleeve 71 are connected by a U-shaped mem-,

ber 84, the lower end of which is connected b a ball and socket joint 85 to a horizontally disposed rod 86, which extends laterally, and is pivotally connected to the upperend of a lever 87, which controls the cone or sliding member of the clutch 10.

When our improved motor truck'is in operation, the sparking devices in the end of the cylinder are controlled by the positions of the casings 18'on the commutators, which casings are all corres ondingly shifted'by movement, of the ban le 62, which imparts rotary motion to the shaft 61; and motion isimparted to the link 21, which is connected to the casing 18 through the various co6perating arts 22, 25, so, 73, 7c, 79, .and 67, which atter part'is fixed on the lower end of the shaft 61.

Simultaneous with the shifting of the casing 1 8 the position of the carbureter valve is changed, owin .to the engagement of the upper ends of t e valve stem 30 with the rod 25, and thus the inlet of air and liquid hydrocarbon to the carbureter is varied as the sparks in the enginecylinders are advanced or retarded.

The degree to which the valves 49- are permitted toopen to allow the inlet of gas or carbureted air is regulated by shifting the handle 64,. wjlgrich, through the action, of the cooperating parts63, 68, 78, 75, 72, 82, 60, 58, 57, 56, and 55, which latter arts are connected to the arms 51 of the co lars 50; and

as said collars are partial] rotated, they will -'move outwardly upon t e screw threaded lugs 47, .thus compressin the springs 53 limits t e inwar movement of the stems 48, andconsequently limits'the area of the openings through'the inlet ports 45. i

Thevalves 49 are opened by suction as the pistons move to the lower ends of the cylinders 6, and when said pistons return to the upper ends of the cylinders, the char es are fired within said cylinders in the usua man,

ner to drive the pistons to the lower ends of the cylinders, and thus imparting rotary mo tion to the engine shaft 8 in the usual manner.

As said engine shaft 8 rotates, the shaft 15 is correspon lingly rotated bythe gearing 16,

and the cams 41 correspondingly actuate the .rods 38 to cause the outer ends thereof to engage against the stems 36, thus opening the exhaust valves at the proper intervals;

proper motion to the lever 87 by means of.

the co-acting parts 65, 69, 77, 74, 71, 84, and 86, which last mentioned part is connected to the u per end of said lever 87 Thus it will be seen how we have constructed a simple, compact motor truck, and provided sim le controlling devices therefor, the handles 0 which controllnig devices are 10- cated immediately ad'acent one another, and which handles an devices readily congoverns t trol the osition of the commutator, which due sparking in the engine cylinders, the valve or valves within the carbureter, the degree to which the gas or carbureted air inlet valves are opened, and the throwing in, orv releasing, of the clutch located on the en-.

gine shaft.
